Powder River Basin (WY, MT) Coal and Coalbed Methane: Evaluating and Revising 100 Years of Studies

The USGS published a USGS Professional Paper in 2010 entitled *After a century: Revised paleogene coal stratigraphy, correlation, and deposition, Powder River Basin, Wyoming and Montana*, (available: http://pubs.usgs.gov/pp/1777/). Information about the coal resources in this Powder River Basin have been published in various forms for over 100 years. The purpose of the pater was to revise, improve and reconcile mapping information and the nomenclature system for this region. Along with the paper, the USGS provides access to a corresponding database. The database contains five tables with the following data: data source (origin of all records in the database); auxiliary information (basin scale maps, stratigraphic information); cross-section information; elevations (top and bottom elevations, in feet, for sands and coals); and detailed well information -- well numbers and names, American Petroleum Institute point identifications, operators, State and County locations, and well type (coalbed methane, oil, natural gas, and coal).
